The alliance's focus includes how we can manage anthropogenic global change according to the principles of sustainable development. The Earth League aims to provide decision makers with multiple options for addressing pressing sustainability issues, by delivering robust background information and enhancing transparency of the choices available.

By coming together in a self-organised alliance, the Earth League members form a united voice in the global dialogue on planetary issues.
